What are the current requirements for obtaining an ED Visa in Thailand?

This may not be strictly true in Patts, as I arrived here on the 1st Feb with a single entry ED issued in London expecting to study 8hrs per week only to be told at the Thai language school that the formal paperwork to get this visa had to show the min study hours of 8hrs pw but for local immigration for extensions 4hrs is adequate and is what the school now schedules for per week for lessons. I have already bought 180hrs tuition so that will be over 12 months then go back to get my paperwork from the school just before every 90 days is up. I do know the rules in Patts is somewhat different from the rest of the country for some reason, so what is suitable here may not be suitable for you if you are in Chiang Mai for example especially when it comes to learning Thai at a private school. Local rules seem to change constantly in Pattaya. One other thing that I will add, it is very obvious there are certain individuals in my class that have absolutely no interest in learning Thai and this is the first class with over 20 students compared to previous classes so whether this studying 4hrs per week is a new thing that a few people have caught onto, well I’m not sure just thought I would let you know the current situation.
